2012 TOYOTA CAMRY HV engine overheat

152 2-1. Driving procedures
CAUTION
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Moving the shift lever to N while the vehicle is moving will disengage the
hybrid system. Engine braking is not available with the hybrid system dis-
engaged.
● During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control,
but the power assist to these systems will be lost. This will make it more
difficult to steer and brake, so you should pull over and stop the vehicle as
soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 470
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 169)
● Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents,
resulting in death or serious injury.
● Always check that all passengers' arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or serious injury.

154 2-1. Driving procedures
CAUTION
■When the vehicle is stopped
●Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any gear other than P or N, the vehicle may accelerate
suddenly and unexpectedly, causing an accident.
● Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the “READY” indicator is on. Apply the
parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

When driving
■
The brightness of the instrument panel lights
When the tail lights are turned on, the meter’s brightness will be reduced
slightly unless the meter brightness level adjustment is set to the brightest
setting.
If the tail lights are turned on when the surroundings are dark, the meter’s
brightness will reduce slightly. However, when the surroundings are bright,
such as during the daytime, the meter’s brightness will not be reduced even
if the tail lights are turned on.
■ Fuel gauge and odometer/trip meter display remain on mode
After the “POWER” switch has been turned off, the fuel gauge and odome-
ter/trip meter display remain on for 10 minutes, enabling the fuel gauge and
odometer/trip meter values to be checked again without having to turn the
“POWER” switch to ON mode.
When confirming the gauges and meters, turn the headlight switch to the
position. Press the display change button to change between the
odometer and trip meter displays.
NOTICE
■ To prevent damage to the engine and its components
The engine may be overheating if the rightmost segment of the engine cool-
ant temperature display is flashing. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.
